Abstract

The influence of initial concentrations of vanillin and sodium bisulfite, and ionic strength of solutions on the stripping equilibrium in a water-octanol system has been studied. Vanillin-bisulfite adduct was found to precipitate from the saturated sodium bisulfite solutions, and the observed distribution ratio of vanillin from organic into water and solid phases attained values of 200–250.
